form of my invention; Fig.2 is a section on theline II--II of Fig. 1, and partly broken away; Fig- 3 is a view similar to Fig. 1 but showing only a portion. of the body of the container and also illustrating a modified construction; Fig. 4 is a section on the line IV-IV of Fig. 2; and Fig. 5 is a longitudinal section showing'still another modification. I

My invention has relation to storage tanks or-containers, and more particularly to tanks or containers for storing acetylene gas which is absorbed by acetone or other suitable absorbent.

The object of my invention is to provide a tank or container of this character which will be strong and free from seams, in which the valve seat is formed within the solid metal head of the container; in which the parts are effectively protected against injury in shipment and in use; and in which means are provided for the collection of the 1 "gas at or near the extreme upper portion of the tank and entirely above the level of the solvent. l

The nature of my invention will be best understood by reference to the accompanying drawings, which will now be described, it being premised, however, that various changes can'be made in the details of con struction and arrangement of the parts without departing from the spirit and scope of my invention as defined in the appended claims.

In these drawings, thenumeral'Q desig nates the body of the container, which is preferably formed from a seamless tube having the end portions thereof forced inwardly and Worked to form the integral heads 3 and 4. The head 4 is formed with the solid metal reduced neck portion 5, which is preferably extcriorly threaded to'receive a screw cap ,6. This neck portion 5 is drilled or b red through to form the centraliopening Spcciiicatlonof Letters Patent.

7 having a screw thread to receive the threaded shank 8 of the usual pressure gage l), which gage is contained within the outer. portion of the cap (5. and may be read through the opening 10 in the end of the cap; l

In constructing the tank or container, after the opening 7 has been bored or drilled, an opening or passage 11 is drilled obliquely through the neck 5 and head t, the

outer end of said opening intersecting the opening 7. This opening 11 is adapted to receive a gas collector pipe or tube 12, whose inner end cnn be extended into the body of the tank closely ad j accnt to its upper wall, the outer end of said tube lying within an enlarged portion or cavity 13, where the opening lljoins the opening 7. The outer end portion of the pipe or tube 12 is pref crably screw-tlneadcd, or is provided with other suitable means for engagement with a suitable socket or key, by means of which the pipe or tube can be withdrawn at any time in case stoppage or other causes renders this necessary. y

let. designates a valve stem, having at its inner end the valve 15. To rcceivetho valve stem and valve the solid metal of the neck 5 is bored or drilled from one side to "form an wrench. This projecting head of the valve stem, as will be readily seen, occupies a position closely within the angle formed by the head 4'and neck 5, and is, therefore, in a position in which it is not likely to be struck and injured in the handling and use of the container.

19 is an outlet passage, which is also bored or drilled in the solid metal of the neck through the side thereof. and communicating at its inner end with the valve-eontaining opening. The outer end portion of the opening .19 is countcrborcd to receive the threaded member 20 of the usual coupling 21.. In charging the tank or container, the valve isscrewed outwardly away from its: seatg'and; the solvent or acetylene gas are charged in througlithe coupling 21. In the use of the tank or container, the valve is open to the proper extent; and the gascollooted by the'pipe or'tube 12'flows outwardly into the cavity 13, thence through the bushing 16 and outwardly through the passage 19.

' 22 designates a fusible plug, which is sented in the solid metal ot'the neck and head, and which controls an escape opening there through, this plug being of any suitable or well known character, and being designed to fuse or melt,1if the temperature. .to which exposed rises to a danger head contributes to the safety of the tank in shipment.

In the modification shown in Fig. 3, I

have illustrated the application'of my invention to a tank or container in which a pressure'gage is not used. In this case, a short cap 6 is employed in lieu of the long cap 6. The opening 7 is closed by a suitable removable screw plug 24, which will close the outer end of the cavity 13. In this figure I have also shown the inner end portion of the collector pipe or tube as being bent into a position more closely adjacent to the head 4. this being done before the head 3 is closed up. This construction enables an asbestos cloth mat 25 to be placed in the end of the tank through which the gas filters and enters the collecting tube without carrying with it any of the loose asbestos with which the tank is filled and which may have a tendency to clog the tube.

The advantages of my invention Will be apparent to those familiar with tanks or containers of this character, since it provides a tank or container which is wholly free from seams; which can be readily manufactured; and in which the parts are effectively protected from injury. The arrangement of the collector pipe or tube, by which it can be extended to the extreme upper portion of the interior of the tank or container, provides for the complete eX- haustion of the gas without drawing oii' any of the solvent. If the collector tube becomes choked or clogged, it can be readily cleaned by forcing a wire or the like therethrough; or it can be readily removed at any time by removing the cap and the gage 9. This tube may, however, be omitted entirely, and the gas allowed to enter directly into the oblique passage 11, since the inner end of 26, as shown in Fig. 5.-

It will be noted that the valve 15 is deepseated within the solid metal of the neckand is thoroughly protected thereby. Its stem .isalso protected by this solid metal and by the screw plug 17, against lateral blows. Themaintenance of the proper conditions of the valve is, therefore, well insured, and the danger of leakage at the valve is reduced to v a minimum.

While I prefer to form-the head 4 and the neck 5 integral with the body 2, yet many of the advantages of my invention may be obtained by forming such head and neck separately and securing them in or-to a body What I claim is 1. A container for fluids under pressure,

comprising a cylinder having an integral thickened end portion forming a combined head and valve'casing, said thickened portion having a collecting passage communieating with the interior of, the body portion of the cylinder and also'having an astake passage communicating with the collecting passage and extending laterally at an angle to the longitudinal axis of the cylinder, and a valve seated within said thickenedi portion and controlling the communication between the collecting and oiitake passages,said valve havinga stem extending laterally within said thickened portion and terminating at its outer end at a point within the circumferential line of said cylinder, substantially as described.

2. A container for fluids under pressure, having a thickened head, said head being provided within the solid metal thereof with two communicating passages extending lat' erally and out through the side of the head,

one of said passages forming a combined gascharging and outlet conduit, and the other passage having a valve seat, and a valve adapted to said seat and contained wholly within the head and; having a laterally protruding stem which lies closely with in the angle formed by thehead and body; substantially as described.

3. A gas container of the character described, having a solid cylindrical head, said head having a central opening for a gage, and also having a gas-collecting passage whose outer end is closed by the gage, and a valved outlet passage communicating with the said collecting passage, said passage, together with the stem of the valve, extends ing in a lateral direction, and a gage-protecting cap engaging the exterior of the cylindrical head, substantially as described.

4. A container for fluids under pressure, comprising a cylinder having an integral thickened end portion forming a combined. head and valve casing, said thickened portion having a collecting passage communicating with the interior of the body portion of the cylinder and also having an offtake passage communicating with the collecting passage and extending laterally at an angle to the longitudinal axis of the cylinder, a valve seated within said thickened portion and controlling the communication between the collecting and oiftake passages, and an ofitake connection connected to said thickened portion and communicating with the ofi'take passage, said connection being. made at a point within the circumferential line of said cylinder, substantially as described.

In testimony whereof, I have hereunto set my hand.
